Note: Left and right same audio mode is not supported in receive data.
To execute 8-bit monaural transmission or reception, use the left channel.
(2) Control Data
Control data is written to or read from by the following registers.
• Transmit control data write: SITCR (32-bit access)
• Receive control data read: SIRCR (32-bit access)
Figure 22.6 shows the control data and bit alignment in SITCR and SIRCR.
